Arguing from Internal evidence

Muslims argue that whereas the Qur'an explicitly says that it was authored by Allah Himself (55:1-2), the Bible makes no such claim. Moreover, whereas you can find the word "Qur'an" several times within the book itself, you do not find a single reference to the "Bible" in the Bible. Do these claims hold any weight? Let us examine.

Firstly, not having a reference to the title within content does not prove anything. I always ask that since Sura al-Fatiha does not contain the word "Fatiha" in it, does that make it false?

Secondly, even if a book claims to come from God, merely the claim does not make it true. If I write a book tomorrow and claim that I received it as a revelation, no Muslim will accept these claims just because I said so.

The reason why we do not find the word "Bible" in the Bible is because the word itself simply means "books". Many Muslims do not know that the Bible is not a single book like the Qur'an. Rather it is a collection of different books written at different times in history. The Qur'an claims that three revelations preceded it, but it calls them by a single name "Al-Kitab" (Sura 10:94).

With that said, we need to ask, do these books claim to come from God, or do the Books of the Bible claim to be Inspired?. The answer is, yes, they do.

The phrase "The word of the LORD came” appears literally hundreds of times in the Old Testament. For example:

"2 The word of the LORD came to him (Jeremiah) in the thirteenth year of the reign of Josiah son of Amon king of Judah, "Jeremiah 1

3"the word of the LORD came to Ezekiel the priest, "Ezekiel 1

The New Testament also makes similar claims:
13 And we also thank God continually because, when you received the word of God, which you heard from us, you accepted it not as a human word, but as it actually is, the word of God, which is indeed at work in you who believe. (1 Thessalonians)

Moreover, we also have in the Bible a consistent pattern of cross authorization. For example, Daniel confirmed the writings of Jeremiah:

Daniel 9:2
in the first year of his reign, I, Daniel, understood from the Scriptures, according to the word of the LORD given to Jeremiah the prophet, that the desolation of Jerusalem would last seventy years.

And then Jesus confirmed the writings of Daniel:
15 “So when you see standing in the holy place ‘the abomination that causes desolation, spoken of through the prophet Daniel—let the reader understand (Matthew 24)

In fact, Jesus at numerous times confirmed the authority of the Old Testament as the Word of God. Speaking of Isaiah, he said "“Today this scripture is fulfilled in your hearing.” (Luke 4:21). Many other examples can be given, but the most famous is this:

18 For truly I tell you, until heaven and earth disappear, not the smallest letter, not the least stroke of a pen, will by any means disappear from the Law until everything is accomplished. (Matthew 5)

Christ also confirmed the Divine Authority of the New Testament when he used the similar words for His own teachings:

Heaven and earth will pass away, but my words will never pass away. (Matthew 24:35)
